Invasion of the Mutant Space Bats of Doom

The Good
One of a bunch of semi-obscure shareware hits, this is an old-school, vertically-scrolling shoot-em-up. The graphics and sound are so-so, but the gameplay shines, being just hard enough to present a challenge whilst not being too hard to play. The power-up structure (basically, more bullets) is simple and effective.

The Bad
On the other hand, it's an ancient shareware game, and it might be quite hard to register it (if you can't find a registered copy). Furthermore, there were other, better games at the time - 'Tyrian' for example.

The Bottom Line
Fast-moving, 'Galaga'-esque five-minute fun blaster from prehistory.

The Good
The gameplay! What else?

The Bad
The graphics are amateurish, the music is stupid, the sound effects are horrible, the title is cheezy and ridiculous and the game is SIMPLY FUN!

The Bottom Line
Fun! Fun and some more fun! What else can you ask for in a shareware game? (... don't even bother to answer)
